Dear Drools' developers and users, I have a problem regarding the size of my Drools' StatefulKnowledgeSession. As I'm working with a 'stateful' session that lives on a web server I have bound this session onto my web session. That means the Drools' session is able to access some facts from preceding calls. The Drools' session lives as long as the web session lives. So far so good. Now I've started to mesure the size of the StatefulKnowledgeSession by usage of heap dumps and some profiling tools. This yielded a size of approximately 5 MB. Is there any approach to optimize the size of a StatefulKnowledgeSession? Apparently this object has a lot of overhead (from my point of view) regarding the Drools Flow and Gouvenor frameworks because I'm not utilizing this frameworks at all (just Drools Expert). Maybe this is an approach to optimize the session's size? If I accept this size, is there a convenient way to serialize the StatefulKnowledgeSession between calls? I'm thinking about storing the whole StatefulKnowledgeSession inside the database or maybe some datastructure apart from the websession. Every call inside one web session would have to lead to a deserialization, application and serialization of Drools' session. Thank you in advance for any reply. Kind regards!
